Allow package lookups across multiple indexes via explicit opt-in (#2815)

Browse source 
## Summary

This partially revives https://github.com/astral-sh/uv/pull/2135 (with
some modifications) to enable users to opt-in to looking for packages
across multiple indexes.

The behavior is such that, in version selection, we take _any_
compatible version from a "higher-priority" index over the compatible
versions of a "lower-priority" index, even if that means we might accept
an "older" version.

Closes https://github.com/astral-sh/uv/issues/2775.
